PURPOSE:To enhance the objectivity, accuracy and efficiency of a test for an automatic operating device in the stored program control system, by giving a test to the system in the state approximate to the original working speed of the system. CONSTITUTION:One of the contents of the registers 2a-2n of the controller 1 that performs a stored program control is selected and stored in the information register 5. Then only the bit designated by the mask register 7 is compared with the contents of the comparison data register 9 at the comparator 8. When the comparison coincidence output is counted up to a prescribed frequency, the sequence control circuit 14 is controlled to read the next working command on the command storage circuit 11. The data of the data storage circuit 10 that is prepared previously is replaced with a data that is selected as a designated data, and a control is given in the order of the sequence of the read-out working command. Then the contents of the information register is stored in the read-out data storage circuit 17. |
